'the collection is welcome and will serve as an excellent entry point to important thought about music linked directly to the antique roots of modern philosophy. Because there are no musical examples and the references to classical languages are translated into idiomatic English, laypersons - even those unfamiliar with the classical period - should not meet obstacles or have accessibility problems. Readers, whether in classics or in music, will find these essays invaluable for making inroads into a period long overlooked in music history. Highly recommended.' M. Dineen, Choice Connect
